adbd: properly close subprocess pipes on Ctrl+C.

When non-interactive sessions exit via Ctrl+C, adbd sends SIGHUP
to the child process to let it know to exit. However, adbd was not
closing the pipes to the child process, so if the subprocess ignored
SIGHUP and continued writing it could fill up the pipe and block
forever while adbd waits for it to exit.

This CL adds the necessary calls to close the subprocess pipe after
sending SIGHUP.
